Considering the effectiveness and safety of battery power used in portable equipment of coal mine, the DS2438 chip was used to realize the power intelligent monitoring of wireless gas detector. Based on the introduction of hardware structure of wireless gas detector and combined with the DS2438 chip, the power control circuit was designed. The calculation principle of supply voltage, current and the remaining capacity was studied. Considering the real-time of system software, the monitoring process of the battery power was detailed designed, and some key procedures were showed. Experiments show that the design of the power monitoring can effectively realize intelligent power monitoring of wireless gas detecdor, and will provide an effective way for power monitoring of underground portable equipment.
